BACKGROUND: Rupture of thoracic aortic aneurysm and dissection into the chest space results in the death of the patient from uncontrolled hemorrhage. The purpose of our study is to evaluate chest radiographic findings that may assist in the rapid detection of nontraumatic disorder in mediastinum and thoracic aorta. MATERIAL AND METHOD: Thirteen consecutive chest radiographs obtained at emergency room of patients with hemorrhage from ruptured thoracic aortic aneurysms or aortic dissections were randomized with radiographs of 8 subjects with nonruptured thoracic aortic aneurysms, 11 subjects with nonruptured aortic dissections, and 20 control subjects. Diagnoses were confirmed by computed tomography(CT) and transesophageal echocardiography(TEE). A retrospective study was performed by assessment of 14 parameters on each of these 52 radiographs to screen the mediastinum and thoracic aortic disorder. RESULTS: Significant difference between patients with mediastinum and thoracic aortic disorder(aneurysm and dissection) and normal subjects occurred in mediastinal/chest ratio>0.25, aortic knob width>4cm, tracheal shift to right loss of paratracheal stripe & azygos vein, and left pleural & extrapleural fluid of chest radiographs(p<0.05). The most useful predictors of mediastinum and thoracic disorder were aortic knob widening above 4cm and combining signs of mediastinum/chest ratio above 0.25 and abnormal aortic arch. These plain radiographic signs had a sensitivity of 9.1~96.9% and a specificity of 40~100% for mediastinum and thoracic aortic disorder. CONCLUSION: The chest radiograph obtained at emergency room remains the best available screening test for mediastinum and thoracic aortic disorder and can be used effectively, though not perfectively, to eliminate unnecessary CT or TEE.

Experimental hydronephrosis was induced in rabbit by ureteral ligation, then deligation followed after certain experimental period as designed. Histopathological changes of the kidney and restoration of hydronephrosis were studied and the following results were obtained: 1. Ligation of the ureter for 3 days produced mild to moderate degrees of tubular dilatation. irregular proliferation and dilatation of small arterioles. Deligation initiates regeneration of the tubules at 1 week and almost normal histology returns by 3 weeks. 2. Ligation of the ureter for 5,7 and 14 days causes marked tubular dilatation, atrophy of the .cortex, and partial obliteration of the glomerulus. By 3 weeks after deligation, the tubules seem to partially regenerate but no significant histological changes were observed. 3. Ligation of the ureter for 21 to 60 days causes formation of scar, marked obliteration of the glomerulus and compensatory hypertrophy of the remaining glomerulus. No morphological restoration was observed by 3 weeks after deligation. 4. It seems that histological restoration starts at periglomerular tubules located closer to the cortex toward the medulla.

Lipoma involving brain and spinal cord is a rare tumor that most commonly located in the midsagittal region. This lesion is usually asymptomatic and has been reported incidentally at postmortem examination. Recently, the CT scan establishes the diagnosis of intracranial lipoma on the basis of typical X-ray absorption and location. The authors experienced a case of intracranial lipoma of occipital lobes. The patient was 7 months-old male who had protruding mass on the occipital region after birth. The mass revealed an uncapsulated lipoma with foca cartilage formation. We report this case with brief review of literatures.

PURPOSE:Factors influencing postnatal growth are innumerable. It is known that genetic factors such as parental height and environmental factors such as nutrition, economic status and hormonal effects are important factors. The purpose of this study was to examine the factors affecting final adult height in normal children. METHODS:753 high school students (513 boys, 240 girls) who live in Seoul were studied. Height and body weight were measured and questionaires about sexual development were examined. We included the subjects who reached fianl adult height. The criteria of final adult height was as following: ages over 17 years in the boys and over 15 years in the girls and growth velocity was less than 1 cm per year. They had no systemic diseases and height standard deviation scores were more than -2.5. RESULTS: 1)Final adult heights were 173.1+/-.1cm in boys and 160.9+/-.7cm in girls. 2)Final adult height significantly correlated with father height(r=0.13, p<0.01), mother height(r=0.25, p<0.01), midparental height(r=0.25 p<0.01) and birth weight (r=0.16, p<0.01). 3)In short final adult height groups, birth weight and midparental height were significantly lower(p<0.05), but puberty onset age, body mass index and economic status were similar to normal stature groups. 4)Final adult height significantly correlated with target height.(r=0.43, p<0.01). In boys, the final adult height was 1.7cm taller than target height on the average. In girls, final adult height was 1.6cm taller than target height on the average. 5)In the group in which final adult height is less than target height, birth weights were significantly lower than those of the groups in which final height is greater than target height. CONCLUSIONS:Among factors affecting final adult height, parent height and birth weight were important. To predict final adult height, target height can be used simply and target height showed significant correlation with final adult height. In the case of showing differences between final adult height and target height, many factors including birth weight will influence the outcome.
